HEINRICH SCHNEIDER, OF ESSEN-ON-THE-RUHR, GERMANY;

PROCESS OF LEACHING OUT I-IOPS.

Specification of Letters Patent.

Patented July 3, 1917.

Application filed August 17, 1912, Serial No. 715,646.

To all whom it may concern:

.Be it known that I, IIEINRIOI-I SCHNEIDER, a citizen of German lihnpire, residing at Essen-on-the-Ruhr, Germany, have invented new and useful Improvements in Processcs of Leaching Out Hops, of which the following is a specification.

The object of the present invention is a process of leaching hops in a hop extracting apparatus provided with a strainer and stirring device, but passing the wort and after-wort through the hops on their way between the refining vat and the copper.

Similar processes are known which consist in leaching the hops in a cooker provided between the refining vat and the copper during the passing of the wort and after-wort by cooking, however, these proc-- esses do not result in fully and perfectly extracting all valuable ingredients of the hops and moreover, the cooking process extracted also the bitter, tart and disagreeable ingredients from the strands, ribs and seeds of the hops which are harmful to the taste of the beer.

It has furthermore been proposed to leach the hops without cooking the same by means.

of Water or a Weak wort avoiding the cooking, however, also these methods do not result in the perfect extraction of all of the useful ingredients and flavors contained in.

the hops because they all require that the hops after having been pressed be subjected to a second digestion and be added to the mash after the third treatment by the wort or water.

with a sieve bottom at suitably spaced from the bottom proper which latter is connected by a valved conduit 0 with a pump z'to which a vertical conduit 6 is secured having near its upper end a two way cock in. A.

conduit 6 leads from said cock to the copper f and another conduit Z to a cooler, not shown in the drawing. The copper f is connected by means of a conduit m with a suitable valve n with the vat a and the valve n controls the communications bef While the hops in the jack are continuously beaten by the stirrer which results in their disintegratlon, while the worts and after worts can also be passed at the running-oil temperature from vat a through the conduit m into the'copper f where they are boiled with the beer contained therein and then passed into the hop-jack c in which they are continuously beaten by the stirrer g g in order to thoroughly disintegrate the hops contained in the ack and from where they are pumped by the pump 7; through the con duit e to a suitable cooler.

I claim:

Process of hopping beer consisting in passing the wort at the running ofl' tern perature through a hop jack in a slow stream, continuously heating it and then pumping it into the copper, then passing theafter-Wort into the copper and boiling it together with the beer contained there in, passing it again through the hop-jack and finally pumping it to a cooler, substantially as described.

In testimony whereof I have signed my name to this specification in the presence of two subscribing witnesses.
